Make components AA accessible
eLife is committed to the AA standard and my guess is (?) Coko will be too. We should probably start to build this in even when we touch components for other purposes.
What is AA? Each of the requirements listed in https://www.w3.org/TR/WCAG20/ is labelled A, AA or AAA - so it’s all the A and AA ones.
However, the standard is about to be updated with this: https://www.w3.org/TR/WCAG21/.
